UN STA ES PATENT OFFICE GEORGE G. GRIFFIN, INDIANAPOLIS, INDIANA.

Be it known that L'Gnonon and State of Indiana, have invented a certain new and useful Hub-Cap Lock for Vehicle-Wheels; and I do here y declare that thefollowing is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, in which like letters refer to like parts.

- 2-2 of Fig. 1. Fig. 3 is a In vehicle wheel hubs and mountings of certain types'there has been difficulty in retaining the caps on the hubs.

that diiiiculty and have a practical construction at the same time.

The nature of the invention will be under-.

There appears herein an axle 1 0 of the.

ordinary type having a spindle 11 with a reduced threaded bolt 12 on the outer end thereof. On the spindle 11 a ball bearing construction is provided consisting of inner rings 13, outer rings 1% and balls 15. These bearing rings are surrounded bya sleeve 16 with an annular outwardly extending flange 17. The outer rings 1 1 and sleeve 16 are shrunk together or otherwise arraned so that they are practically securedtoget er and collar 19 on the axle limits the inward movement of the sleeve 16. The hub 20 surrounds the sleeve 16 and fits against its flange 17 and is keyed thereon by a key :21 A washer 22 is held against the-bearin" a ring 13 by a illlt 23 on the bolt '12. l A disk 60 surrounds a nut 23 and is held in place-against sleeve 16 by ca 26. The outer end oi sleeve 16 is external I threaded at to receive the internally threaded portion of said cap 26. The cap has a central angular nut extension 27 to which a wrench may be applied for tightening and releas ing the cap. Said capoverlam a portion of the disk 60 near its periphery so that when the cap is in place, it clamps the disk 60 to sleeve 16 and the hub against flange l7, so as to make parts 14;, 16 and 20 practically the hub.

' 'A ratchet 30 is secured to the disk 60 by I Specification of Letters Patent.

' Gmrrni, .acitizen ofthe United States, and a resident of Indianapolis, county of Marion,

The object of this invention is to overcome" 'l-IUB-OAP LOCK FOR VEHICLE-WHEELS Patented an. 4, 1916.;-

inclined in the right-hand direction, that is, v

inthe same direction as the capis turned while being put on and tightened. -In the nut extension 27 of the, cap there is a pair .ofinwardly extending cars 32 in which a pawl lever 33 is fulcrumed betwee'n its ends and the parts are arranged so that the inner endof said pawl lever rides on the ratchet and enters the spaces between the ratchet teeth. The inner end of such pawl lever is forced into locking engagement with said ratchet by a spiral Spring 35 whichsurroundsa rod 36 and lies between the pawl lever 33 and a bearing 37 in the nutextension 27 of the cap; The rod 36 lies radially within the nut extension 27 and at one end a 7 projects outwardly'beyond the same so that 1 r said rod may be pushed longitudinally inward against. the resistance of 'the'spring 35 and by means of'a collar 38 on saidrod and which engages the pawl lever'33, may release the pawl lever from the ratchet, when it is desired to release or remove the cap. 7 \Vith this construction the cap is screwed into place and as it is thus screwed into place the pawl lever 33 rides over the ratchet 30 until the capgets screwed tightly into place and then the cap cannot return a person shall force the rod 36 inward and release the pawl'lever. Yl henthis is done,

the .cap can be unscrewed as usual,

Inthe claims the word "hub is used to I mean the hub construction including the parts rigid and rotating with the hub.

The invention is:' j v r 1. 17118" combination of'the hub of a vehicle -wheel suitably threaded, a cap arranged y or be released in any mann'er excepting when to screw on said hub, a ratchet disk secured centrally in cp-nnection with saidhub, bearing-means extending inwardly from said cap, a pawl lever pivoted in said bearing means betweenits ends parallel with the axis of the ratchet disk and with theinner end thereof adapted to-enter a notch'in the ratchet disk, a rod mounted radially in said cap with one end projecting outwardly therefrom so as to be longitudinallylmow able, and a stop on said rod for engaging one end of said pawl leiier and releasing the v I rection. r

2.. The combination lot the hub of a vehicle wheel suitably threaded, ai'cap arranged to screw on said hub, gitratchet dlsk secured same when ,the rod isjactuated in one di-' centrally in connection with said hub, beering means extending inwardly from said cap, a pawl lever plvoted 1n seed beermg means between its ends with the inner end thereof adapted to enter a xwteh in the ratchet disk, a rod mounted in said cap with one end rejecting outwardly therefrom and soes to e longitudinally; mevable, a stop on said rod forengagingthe end of said pawl lever and releaslng the Same when the rod is actuated in one dlrection, and; Ya sue sees rounding said rod acting against s lever for forcing it in the other clirec me locking engagement,

- In wlt ness whereof, I have efiixerl my eigneturein the presen Witnesses herein named.
